Application med April 2, 1925. Serial nmcaoea Our invention relates topaper cutters and more particularly to cutters for cutting off sheets ofany required length from paper fed from rolls of paper and the objectistoprovide a simple mechanism which will be convenient and easilyoperated and which will automatically return to inoperative positionafter a cutting operation. Other objects and advantages will be fullyexplained in the 7 following description and the invention will be moreclaims.

Reference is had to the accompanying drawings whichform a part of thisapplication.

particularly pointed out in the cutter.

form 1 which is supported on upright frame members 2 which are; providedwith crossbeam braces 3. The cutter consists of a rectangular frame 4and a small wire or cord 5 which is held taut by the frame 4. "Thecutter is adapted to move vertically and a slot 6 is made in theplat-form 1 for the passage of the wire 5. A guide is provided for theframe'4 and this guide consists of two uprights 7 which are mounted inthe platform 1 and attached to cross-braces 9 and provided with slots 8for movement of the frame 4. The frame 4' is held in the elevatedposition by weights 10 to which are attached cords 11 which are extendedupwardly and over idle pulleys 12 and then extended downwardly attachedto the upper side of the frame 4. The pulleys 12 are mounted in theupper ends of uprights 7. For the cutting operation, a foot lever 13 isfulcrumed on a cross-beam 3 and a cord 14 is attached to the lever 13and extended upwardly over an idle'pulley 16 which is mounted on across-beam 15. The cord 14 no is then extended downwardly and run underan idle pulley 17 which is mounted on the crossbeam 9 and the cord14 isthen extended upwardly and attached to the lower side of the frame 4.The paper to be cut is mounted on rolls 18 which are journaled insuitable Fig. 1 is a front elevation of the paper The paper cutter isprovided with a platbearings 19 which are. attached totheupri hts 2. 1Different rolls are provided for different widths of paper. The'paper tobe cut is drawn acros'sthe platformand over the slot 6 and in passingLover the platform 1, the paper passes between small rollersfZQ andv2l;which,serve as guides and also" as holders. The upper roller 20 isheldyield ingly against the paper by springs 22. Different pairs ofrollers 20 and 21 are provided for paper of different widths. The

rollers 20 and 21 will hold the paper with sufiici'ent friction toprevent thepaper from falling back from the back part of the piatformafter a portion of paper is cutfrom the sheet.

The opening through the platform forthe cutter may be made wide andadjustablev bars 2-3 provided for attachment to the plat. form atdifierentfadjustments. The bars 23' .75 are spaced apart to form theslot 6. v In this manner the slot 6 can be adjusted to the proper placeto let the cutter 5'pass freely therethrough.

' I In operation, a sheet of paper is drawn over the top of the platformand across the slot 6 to obtain the required length of paper. H Thelever 13 is then'presse'd down by the foot y to cause the cutter 5 tocut the sheet of paper.

lVhat we claim, is, i 1. A papercutter comprising a platform and a frametherefor, said platform having, passage ways for a cutter, means forpositioning paper to be drawn across said platform, a cutter movablevertically through 9 0 said platform, a guide for said cutter in itsvertical movements, a foot lever operatively connected to said cutterfor moving the cutter downwardly, and means for automatically returningthe cutter to inoperative position consisting of idlers j ournaled inthe top of said guide, cords attached to said cutter and extended oversaid idlers, and weightsattached to. said cords. i

2. Apaper cutter comprising a platform 19 having a slot therethrough fora cutter, a-

frame for said platform, cutter'movable through said slot, a guide forsaid cutter rigid with said frame, a foot lever operatively connectedwith saidcutter for forcing said cutter down throughsaid platform, andmeans for automatically returning the cutter to inoperativepositionconsisting of idlers journaled in the top of said. guide, cords attachedto said cutter and extended over :5
